'FUSE-CASE.

Specification of Letters Patent. Patentggd Jun@ 27, 19116:,

Application filed March 8; 1916. Serial No. 82,869.

To all whom t may concern Be it known that I, HERMAN L WITT- sTEIN, a citizen of the United States, resid ing at Paulsboro, in the county of Gloucester, State of New Jersey, have invented a new and useful Fuse-Case, of which the following is a specification.

My invention consists of a case for holding a fuse in a steady and firm manner, whereby the powder, pellets, or like material therein will not break, and so cause the fuse to be dangerous in transit or handling and the fuse is not liable to be discharged by' positive or direct pressure on its nose while within the case.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may bev varied, as long as they are included in the scope of the claims.

Figure l represents a perspective view of a fuse case embodying my invention. Fig. 2 represents a central longitudinal section thereof showing also a fuse in the case. Fig. 3 represents a bottom plan view of the cover of the case.v Fig. 4 represents a top or plan view of the body of the case. Fig. 5 represents a plan view of a pad employed,

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates a case for holding a fuse, the same being formed of the body 2, and the cap or cover '3, which excepting the features of my invention applied thereto (especially .to the' cap) are of usual construction. V

Rising from the center bf the top wall of the cap 3 is the convex dome 4, the underside or inner wall of which forms the concave seat 5 -which extends upwardly or outwardly and accords or comparatively accords with the nose 6 of a fuse, a form of which latter is shown in Fig. 2. In said seat is placed the concavo-convex pad 7 of pliable or cushioning material, the same being adapted to have the nose of the fuse contact therewith, forming' a gasket therefor. It will be seen when the fuse is placed in the body of the case and the cap applied thereover the wall ofthe seat 5 embraces the nose of the fuse, and the pad 7 forms a tight joint for said wall and nose, serving also a pliable cushion to press the fuse on the bottom of the box and so hold it firmly, buty softly, thereon. By this provision the fuse lis centralized in the body 2 and so prevented from shifting in the case, and thus the powder, pellets, or

fother like material in the fuse will not break, which otherwise is dangerous in its nature. The top wall 8 of the cap is depressed from the circumferential rim of the v top of the cap to its lowest point 9 where it forms a circumference from which the dome 4 rises, leaving the crown of the latter slightly below the plane of said rim as shown, or at leastnot above said plane, while it may be parallel with said plane, as here-- inbefore stated, whereby it presents no obstacle on the top of the cap to the placing of cases flat one on the other for packing,

shipping and storingl and avoids a close contact with any flat surface that may rest on said rim yand so relieving the nose of the fuse of the direct or positive pressure of such surface which otherwise is dangerous in its nature. It will be noticed also that the under wall of said circumference 9 of the dome 4 surrounds the periphery of the pad 7v and acts in a manner as a shoulder preventing lateral nshifting of said pad from its seat on the under concave side of the dome 5. Within the body is the packing 10 of corrugated paper or other material, the same being located on the inner wall of 'said body and so interposed between said wall and the side of the fuse forming a pliable wrapper for the latter, the leffect of which is evident Having thus described myinvention what I claimvas new and desire to secure by Letters Patent is 1. A case of the character stated having on an, end member thereof a dome within the rim of said member, the crown of said dome 'being approximately slightly below the plane of said rim adapting said crown to avoid actual contact with any flat 'surface that may rest on said rim. l

2. A. case of the character stated having on an end member thereof a dome, the crown of which is slightly below the plane of the surrounding rim of said end, the under side of said dome forming a concavity, and a body of pliable material occupying said concavity.

3. In a fuse case, an end member for the body thereof formed of side and top walls,

and a dome in the top Wall rising therefrom, a dome rising from the base of said dethe Crown thereof being approxunzttely on pressed portion, the crown of said dome bethe plane of the rim of said cup. ing approximately on the plane of said rim. 10

4. In n. fuse onse, an end member for the HERMAN L. "WITTSTEIN.V 5 body thereof, formed of side and lcop Walls, Witnesses:

a portion of the top Wall being depressed JOHN A. VVIEDERSHEIM, from the circumferential rim of the. cnn. :md N. BUSSINGER.
